    In the given structure of a compound, the correct various bond moments direction involving are shown as

    A)  \[Br\underline{\leftarrow }N\underline{\leftarrow }C{{H}_{2}}\underline{\to }Si{{H}_{2}}\underline{\leftarrow }C{{H}_{2}}\underline{\to }O\underline{\leftarrow }C{{H}_{3}}\]

    B)  \[Br\underline{\leftarrow }N\underline{\leftarrow }C{{H}_{2}}\underline{\leftarrow }Si{{H}_{2}}\underline{\leftarrow }C{{H}_{2}}\underline{\to }O\underline{\leftarrow }C{{H}_{3}}\]

    C)  \[Br\underline{\leftarrow }N\underline{\to }C{{H}_{2}}\underline{\leftarrow }Si{{H}_{2}}\to C{{H}_{2}}\underline{\to }O\underline{\leftarrow }C{{H}_{3}}\]

    D)  \[Br\underline{\leftarrow }N\underline{\to }C{{H}_{2}}\underline{\to }Si{{H}_{2}}\underline{\leftarrow }C{{H}_{2}}\underline{\to }O\underline{\to }C{{H}_{3}}\]

    Correct Answer: C

    Solution :

    Bond moments in a compound is shown by electron pushing arrows. It is the movement of electrons from an electron rich site (a lone pair of electrons or a bond) to an electron poor site and it is generally shown from less electronegative to more electronegative atom.
